RIDIN'G- HARROW.

SPECIFICATION forrning part of Letters Patent No. 269,051, datedDecember 12, 1882.

Application filed August 29, 1882. (No model.)

To all whom 'it may concern Be it known that I, GODFREY J. HANNI, of St.Jacobis, in the oounty of Madison and State of Illinois, have invented acertain new and useful Improvement in Riding Harrows, of which thefollowing is a full, clear, and exact description, reference being hadtoflthe ac- *companying drawings, i'orming part of this specitication,in which- Figure 1 is a perspective view; and Figs. 2 and 3, transversesections taken on line 3 3, Fig. 1, Fig. 2 showing' the harrow set withthe teeth pointing forward, and Fig. 3 showing it set with theteethiuclined backward.

- My invention relares to a riding-harrow,and one in which theteeth maybe madeto pointforward for loosening' the ground when it is hard andpacked, orassunie avertical position, or bJ made to incline backwardlorlight harrowing. Tin-re are also scrapers combined in the harrow,which act to crush olods and level the ground.

My invention consists in Vvarious novel features, hereinafter fullydescribed and claimed.

A A' represent the side strips or pieces of the harrow, connected at therear' by toothbars B B', and at the front by a tooth-bar, U. and asemper-bar, D. 'lhe tooth-bars are all secured to the side piecesin-such a manner that they will rock freely in their bearings. The tworear tooth-bars have upward-projecting arms E El, respectively securedto them by clips F F' or by other suitable mea-ns. The upper ends ofthese arms are connected together and to a lever, G, by means of a baror bars, H, prelerably two, as shown in Fig. 1. The arms connect withthe bars by means of pivot-pins I and l', the latter, l', workingin aslot, J, in the arm E', so that the parts can operate. The lower endofthe lever G is pivoted to the scraper-bar D,or to a ratchet-plate, K,srcured to the bar, preferably to the latter, as shown.

Upon the lever, just abovethe ratchetplate, so as to engage the teeththereof, is pivoted a pawl, L, with its rcar end turned so thatit can beoperated by the foot of the driver and its forward end having a weight,L', which keeps it in contact wiihthe teeth of the ratchet-plate exceptwhen raised by the foot. Thus it will be seen that by Operating thelever either of the described positions can be given to the teeth of thebars B B', and the iuclination of the teeth of the bar B' relative tothose of the bar B can be changed by puttin g the pivot-pin l' throughh'les H' in the connecting-bars H.

The teeth of the front bar, O, always incline backward;buttheirinclination may bechanged by means ot' an arm,M, secured to thebar and extending back over the scraper-bar D, a slot, M', in its endreceiving a bolt, N, extending up from the scraper-bar, with a nut, N',for

regulatiug the position of the arm, and consequeuty the po-ition of thebar O.

Secured to the bar -U is a strip, O, projecting beneath the bar, for thepurpose of breaking1 clods and leveling,` the ground, and the semper-barI) is l'or the same purpose, the lower front corner prel'erably beingrounded, as shown.

P represents the driver-,s seat, secured to the scraper-bar D, and Q thedraft-bail, which is also securi-d to the scraper-bar. z

' To prevent the forward end of the harrow descending toofarintoravitiesin the ground such as dead-t'nrrows, &c.-and the consequent tilting' upoi the rear end, I secure a yoke, R, to the strip or bar (1,,whichstraddles the bail, as shown, and which has aV pin, S, above the bail,the pin being adjnstable by means of 8o 4pieees, A A', rockint),`tooth-bars B B', and

s :raper-bar D, the tooth-bars beingconnected to the scraper-bar bymeans of arms E E', connecting hm or bars H, le'ver G, with weightedpawl L, and ratchet-plate K, all subsiantially as shown and described,and Operating as set forth.

2. In a harrow, the combination ot' side strips, AA', scraper-bar D,androckiug toothbar G, the bars D and O being connected by an arm, M, boltN, and nut N',Isubstantially as shown and described, for the purposo setforth.
